Nonlinear techniques for forecasting solar activity directly from its time series
This paper presents numerical techniques for constructing nonlinear predictive models to forecast solar flux directly from its time series. This approach makes it possible to extract dynamical in variants of our system without reference to any underlying solar physics. We consider the dynamical evolution of solar activity in a reconstructed phase space that captures the attractor (strange), give a procedure for constructing a predictor of future solar activity, and discuss extraction of dynamical invariants such as Lyapunov exponents and attractor dimension
Effects of Enamel Paint on the Behavior and Survival of the Periodical Cicada, \u3ci\u3eMagicicada Septendecim\u3c/i\u3e (Homoptera) and the Lesser Migratory Grasshopper, \u3ci\u3eMelanoplus Sanguinipes (Orthoptera).
We present information compiled from several studies on the effects of methods for marking individual arthropods on their longevity and behavior. Results from our own research on effects of enamel paint marking on two in- sect species, the periodical cicada, Magicicada septendecim, and the lesser migratory grasshopper, Melanoplus sanguinipes, are also presented. Neither species showed any adverse survivorship or behavioral effects from marking
Studies on the Reduction of Radon Plate-Out
The decay of common radioactive gases, such as radon, produces stable
isotopes by a sequence of daughter particles with varied half-lives. These
daughter particles are a significant source of gamma, neutron, and alpha
particle backgrounds that can mimic desired signals in dark matter and
neutrinoless double beta decay experiments. In the LUMINA Laboratory at
Southern Methodist University (SMU), studies of radon plate-out onto copper
samples are conducted using one of XIA's first five UltraLo 1800 alpha
counters. We present results from investigations into various mitigation
approaches. A custom-built copper holder (in either plastic or metal) has been
designed and produced to maximize the copper's exposure to 220Rn. The 220Rn
source is a collection of camping lantern mantles. We present the current
status of control and experimental methods for addressing radon exposure
levels.Comment: 4 pages, 1 figure, Conference Proceedings for Low Radioactivity

Constitutional Law- Civil Rights- Private Schools Prohibited from Excluding Qualified Children Solely Because They Are Black
All major school desegregation decisions through 1975 involved public schools, and were based on provisions of the fourteenth amendment. This constitutional remedy, however, requires the presence of state action before being triggered. Commencing with the Supreme Court\u27s earliest public school desegregation decisions, and accelerating with the finding of affirmative duties of southern school districts to desegregate, private educational institutions following racially exclusionary admittance policies were founded. Such private discrimination generally has been considered to be beyond the scope of the fourteenth amendment. Moreover, parents that patronize such institutions have sought support in Supreme Court cases which confer constitutional protection upon familial decisions whether to bear, and how to rear, their children. However, these rights have not been held to be exempt from reasonable governmental regulation

Miniature modular microwave end-to-end receiver
An end-to-end microwave receiver system contained in a single miniature hybrid package mounted on a single heatsink is presented. It includes an input end connected to a microwave receiver antenna and an output end which produces a digital count proportional to the amplitude of a signal of a selected microwave frequency band received at the antenna and corresponding to one of the water vapor absorption lines near frequencies of 20 GHz or 30 GHz. The hybrid package is on the order of several centimeters in length and a few centimeters in height and width. The package includes an L-shaped carrier having a base surface, a vertical wall extending up from the base surface and forming a corner therewith, and connection pins extending through the vertical wall. Modular blocks rest on the base surface against the vertical wall and support microwave monolithic integrated circuits on top surfaces thereof connected to the external connection pins. The modular blocks lie end-to-end on the base surface so as to be modularly removable by sliding along the base surface beneath the external connection pins away from the vertical wall
